STUD-SETTING MACHINE.

Specification of Letters Patent.

Application led January 13, 1913. Serial No. 741,769.

To all whom t may concern:

Be it known that I, ALFRED S. KEMP, a subject of the King of England, residing at Leicester, Leicestershire, England, have in-l vented certain Improvements in Stud-Setting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for setting lacing studs in the uppers of boots or shoes or in other sheet material.

The invention is herein shown as embodied in a machine for setting astud which consists of a circular head or crown which, when the stud is inserted, forms the projecting part for retaining the lacing. The head or crown is connected by a central neck with a flat circular flange while below the flange is a tubular shank or barrel adapted in the operation of the machine to be upset or clenched against one side ofthe stock, the flange bearing upon the other side.

One object of the invention is to provide a machine of such construction that studs of the character above discussed will be supported during the setting operation entirely, or in a large part, by the head or crown and the iiange thus relieved of pressure which would tend to distort it.

A feature of the invention consists in the provision of an anvil having a iange to position the neck of the stud and an abutment to support its head or crown during the setting operation. As herein shown the anvil is arranged to be withdrawn trans` versely and the clenched stud thus released after the setting operation, so that the work and the stud are free to be moved in the feeding operation. In orderl that the anvil flange may correctly position the neck of the stud and at the same time impart little stress to the flange of the stud, the anvil flange may be made flexible or resilient and its edges may be beveled in order to center the neck. f

It is believed that no machine for setting studs has ever before been provided with a transversely movable anvil having a yielding member for supporting the flange of the stud.

Other features of the invention will be apparent from the accompanying descriplected for purposes of illustration and shown Patented Oct. 24, 1916. y

in the accompanying drawings, in which,-e

Figure 1 is a view in side elevation, partly 1n section, of portions of a stud setting machine showing a stud 1n position to be inser-ted in the stock; Fig. 2 is a similar view showing the parts of the machine in the position they occupy when the anvil is withdrawn after the clenching operation; Fig. 3 1s a fragmentary view of the stud carrier seen from the left in Fig. 1, and Fig. 4 is a` plan view'lof the stud carrier.

As illustrated in the drawings, the invention is embodied in a setting machine of the type described in Letters Patent of the United States No. 811,839, granted February 6, 1906, on an application of P. R. Glass. As in the machine of said patent, the present machine comprises a reciprocatory plunger 23 arranged in line with and' below an upsetting die 26 and actuated'by a cam on the main shaft 18. This plunger, with its associated parts, constitutes theV stud carrier to which the studs are fed from a hopper by the raceway 24. They are transferred from the raceway to the stud carrier by mechanism not shown.-

Adjustably connected with the upper end guideways for the anvil 30. The anvil isrecessed so that it forms tw'o arms and upon the lower arm 32 is located a rigid cupped abutment shaped to fit the crown of a stud. The upper arm 34 of the anvil is in the form of a slotted plate the sides of which engage the neck of a stud and position the stud with its head fitting into the cupped abutment ofthe lower arm.

At its outer side the anvil 30 is connected by a pin 36 to a head 33 mounted upon the upper end of a stem 40 which is received in a socket formed in one arm of a cam lever 42. The cam lever 42 is pivoted between ears on the frame of the machine and has a cam roller 17 arranged to run upon the cam 16 on the main shaft. The cam 16 is so shaped as to swing the cam lever V42 outwardly after each setting operation and so Fig. 2. Movement of the anvil in the opposite direction is eected by a spring following the outward movement of the anvil there is provided a stationary pin 50 which is set in the sides of the member 20 and extends between the upper and lower.

arms of the anvil, being disposed, in respect to height, opposite to the periphery of the head of a stud in the anvil.

The upper arm 34 of the anvil may be made of spring material or otherwise rendered flexible so that, while oiiering suficient support to insure the proper location of the stud, it will yield should the head of the ystud be so short as to prevent it from seating fairly in the cupped abutment of the lower arm of the anvil.

In the initial position of the machine the plunger 23 is lowered and the anvil moved inwardly into register with the raceway as shown in Fig. 1. A stud is then delivered and the setting operation eected by simultaneously elevating the s tud carrier and depressing the upsetting die 26. The anvil is next withdrawn as shown in Fig. 2 and the head of the clenched stud released, whereupon the parts of the machine are returned to initial position and the work with the stud is fed into position for the next stud.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States:

l. A machine for setting lacing studs having, in combination, an upsetting die, a cooperating stud carrier having a transversely movable anvil provided with a yielding flange for supporting the neck of a stud and a portion beneath the iange, spaced there' from and shaped symmetrically for rigidly supporting the head of the stud against the setting pressure, said anvil being moved after the setting operation, together with its yielding liange and spaced supporting portion, to permit the clenched stud to be advanced with the work in a direction at substantially right angles to the path of the anvil. Y

2. A machine for setting lacing studs having, in combination, an upsetting die, a cooperating stud carrier having a transversely movable anvil provided with a rigid abutment for engaging the head of a stud and a yielding flange above the abutment for engaging the neck of the stud.

8. A machine for settinglacing studs havking, in combination, an upsetting die and raceway, a plunger movable from one to the other to receive and clench a stud, and an anvil mounted for transverse movement in the plunger and having a rigid cupped abutment for holding the hook head and a slotted yielding plate spaced from said abutment and arranged to position the neck of a stud during the setting operation.

In testimony whereof I have signed my name to this speciication in the presence of two subscribing witnesses.

ALFRED STEPHENSON KEMP.
